[0027] Specifically, Figure 1 , Figure 3 As shown, when in use, the positioning block 602 and the positioning bolt 605 are used to limit the assembly block 601 left and right and up and down, so that the inner wall of the assembly block 601 fits the outer wall of the stirring shaft 3, and prevents the assembly block 601 from rotating dislocated with the stirring shaft 3, thereby ensuring the stability of the installation of the stirring blade 5 and ensuring its stirring effect;

[0029] The up-and-down reciprocating mechanism 8 includes a lifting frame 801 sleeved on one end of the outside of the horizontal rotating shaft 7, and the bottom end of the lifting frame 801 is welded to the top end of the lifting rod 12, a left tooth plate 802 is installed on one side of the lifting frame 801, and a right tooth plate 803 is installed on the other side of the lifting frame 801, and a half gear 804 is sleeved on the outside of the horizontal rotating shaft 7 inside the lifting frame 801;

[0031] Specifically, Figure 1 , Figure 2 As shown, when in use, the special structure of the half gear 804 is used to cooperate with the left and right gear plates 802 and the right and left gear plates 803 to achieve the up and down reciprocating movement of the lifting frame 801, thereby ensuring that the scraping ring 11 continuously scrapes the inner wall of the mixing drum 1 during the mixing process;

[0032] A lifting rod 12 is installed at the bottom end of the upper and lower reciprocating mechanism 8;

[0033] A guide groove with a rectangular cross section in top view is provided at the bottom end of the lifting rod 12, and the top end of the square column 13 is inserted into the guide groove. The lifting rod 12 and the square column 13 form an up and down sliding structure through the guide groove.

[0034] Specifically, Figure 1 , Figure 4 As shown, when in use, the square column 13 is used to limit the moving direction of the lifting rod 12, thereby ensuring the stability of the lifting rod 12 moving up and down, thereby ensuring the stability of the movement of the lifting frame 801;

[0037] The outer edge of the top of the scratch ring 11 abuts against the inner wall of the mixing drum 1;

[0038] Specifically, Figure 1 , Figure 4 As shown, when in use, the structure of the scratch ring 11 is utilized so that when it scratches the inner wall of the mixing drum 1, the concrete can flow downward along the inner wall of the scratch ring 11 and approach the rotation axis inside the mixing drum 1, thereby facilitating the mixing blades 5 to effectively mix the concrete.

[0039] Working principle: When the utility model is used, firstly, concrete raw materials are poured into the interior of the mixing drum 1, and the servo motor 2 is started, so that the mixing shaft 3 drives the mixing blades 5 to rotate, so as to achieve the mixing effect of the concrete raw materials, and during the rotation of the mixing shaft 3, the second bevel gear 10 is synchronously driven to rotate, and since the second bevel gear 10 and the first bevel gear 9 are meshed with each other, the first bevel gear 9 drives the transverse rotating shaft 7 to rotate;

[0040] Secondly, the transverse rotating shaft 7 synchronously drives the half gear 804 to rotate during the rotation process. When the tooth side of the half gear 804 moves to the left, its teeth mesh with the left tooth plate 802, thereby driving the lifting frame 801 to descend. When the teeth of the half gear 804 rotate to the right, they mesh with the right tooth plate 803 to drive the right tooth plate 803 to descend, thereby realizing the up and down reciprocating movement of the lifting frame 801, making the lifting rod 12 move up and down along the square column 13, and making the rubbing ring 11 move synchronously, that is, the mixing blade 5 is stirring the concrete while the rubbing ring 11 scrapes the inner wall of the mixing drum 1 up and down, so as to reduce the adhesion of the concrete and prevent the concrete from solidifying on the inner wall.

[0041] Finally, by screwing the locking nut 606 to separate it from the positioning bolt 605, and then moving the positioning bolt 605 laterally out of the positioning hole 604, moving the assembly block 601 outward to move the positioning block 602 out of the interior of the positioning groove 603, the stirring blade 5 can be removed from the stirring shaft 3, so as to achieve the effect of individually disassembling and replacing the stirring blade 5.
